Part 1: Choosing the Correct Wire Size for a DC Circuit ... In addition, the DC Wire Selection Chart shown below assumes a wire insulation rating of 105°C. A lower rating will decrease the current carrying capacity of the wire. To use the chart included with this technical brief, follow the instructions below. Choosing the correct wire A Locate the CURRENT IN AMPS of your appliance across the top of the chart. Most electrical products include a rating label, or you can find the amperage rating in the documentation that came with the product. CIRCUIT PROTECTION Blue Sea Systems Circuit length is 50’, circuit type is ‘non critical’, and correct wire size is 4 AWG. The Circuit Wizard, at circuitwizard.bluesea , is a resource for a more detailed treatment of wire size selection for DC circuits. It allows you to input detailed information including wire insulation temperature rating and other derating factors. Part 1: Choosing the Correct Wire Size for a DC Circuit ...

CIRCUIT PROTECTION Blue Sea Systems If it is over maximum, use a larger wire in the circuit. Review Part 1 for more information on choosing wire size for a DC circuit. Follow the steps to choose fuse amperage and a fuse holder or fuse block. Choose the Fuse Amperage In this step, find appropriate fuse amperage within a range. A Find MAXIMUM FUSE AMPERAGE by following your AWG wire size (from Part 1 of this series) across the Fuse Amperage Chart on page 2. Part 2: Select a Fuse and Fuse Holder For Your DC Product ... If this fuse value is too high to protect the wire, use a bigger wire in the circuit. Review Part 1 for more information on choosing wire size for a DC circuit. Follow the steps to choose fuse amperage and a fuse holder or fuse block. Choosing the Fuse Amperage. In this step, find appropriate fuse amperage within a range of minimum and maximum Boat Wire | Choose the right boat wire for the job using ... The table below shows wire sizes (purple) for low voltage DC circuits (under 40 volts) based on the distance (red) from the power source to the appliance and the current draw (blue) of the unit. Wire sizes specified in the table should limit voltage drop in a 12 volt DC circuit to under 3%. Choosing the right type of wire? Electrical Engineering ... Strictly looking at your current requirements, 18 AWG could do just fine, but most 18 AWG wire won't be rated for that voltage. In a house, you'd be required to use 14 2 wire (14 AWG, 2 conductors plus ground), but I have no idea if THHN is rated for auto temperatures.
